Blood is a bodily fluid in animals that delivers necessary substances such as nutrients and oxygen to the cells and transports metabolic waste products away from those same cells.In vertebrates, it is composed of blood cells suspended in blood plasma. Plasma, which constitutes 55% of blood fluid, is mostly water (92% by volume),[1] and contains dissipated proteins, glucose, mineral ions, hormones, carbon dioxide (plasma being the main medium for excretory product transportation), and blood cells themselves. Albumin is the main protein in plasma, and it functions to regulate the colloidal osmotic pressure of blood. The blood cells are mainly red blood cells (also called RBCs or erythrocytes) and white blood cells, including leukocytes and platelets. The most abundant cells in vertebrate blood are red blood cells. These contain hemoglobin, an iron-containing protein, which facilitates transportation of oxygen by reversibly binding to this respiratory gas and greatly increasing its solubility in blood. In contrast, carbon dioxide is almost entirely transported extracellularly dissolved in plasma as bicarbonate ion.Vertebrate blood is bright red when its hemoglobin is oxygenated. Some animals, such as crustaceans and mollusks, use hemocyanin to carry oxygen, instead of hemoglobin. Insects and some mollusks use a fluid called hemolymph instead of blood, the difference being that hemolymph is not contained in a closed circulatory system. In most insects, this "blood" does not contain oxygen-carrying molecules such as hemoglobin because their bodies are small enough for their tracheal system to suffice for supplying oxygen.Jawed vertebrates have an adaptive immune system, based largely on white blood cells. White blood cells help to resist infections and parasites. Platelets are important in the clotting of blood. Arthropods, using hemolymph, have hemocytes as part of their immune system.Blood is circulated around the body through blood vessels by the pumping action of the heart. In animals with lungs, arterial blood carries oxygen from inhaled air to the tissues of the body, and venous blood carries carbon dioxide, a waste product of metabolism produced by cells, from the tissues to the lungs to be exhaled.Medical terms related to blood often begin with hemo- or hemato- (also spelled haemo- and haemato-) from the Greek word αἷμα (haima) for "blood". In terms of anatomy and histology, blood is considered a specialized form of connective tissue, given its origin in the bones and the presence of potential molecular fibers in the form of fibrinogen....Show less

Sperm is the male reproductive cell and is derived from the Greek word (σπέρμα) sperma (meaning "seed"). In the types of sexual reproduction known as anisogamy and its subtype oogamy, there is a marked difference in the size of the gametes with the smaller one being termed the "male" or sperm cell. A uniflagellar sperm cell that is motile is referred to as a spermatozoon, whereas a non-motile sperm cell is referred to as a spermatium. Sperm cells cannot divide and have a limited life span, but after fusion with egg cells during fertilization, a new organism begins developing, starting as a totipotent zygote.[citation needed] The human sperm cell is haploid, so that its 23 chromosomes can join the 23 chromosomes of the female egg to form a diploid cell. In mammals, sperm develops in the testicles and is released from the penis. It is also possible to extract sperm through TESE. Some sperm banks hold up to 170 litres (37 imp gal; 45 US gal) of sperm.This is all about sperm. Please DO NOT dump unrelated content here or more than 5 photos or videos of yourself cumming. We get the idea after the first two. All violators will be removed promptly...Show less

This is a special (and exclusive!) place for women and girls to discuss total or partial female nullification. Nullification involves the voluntary removal of body parts. Body parts that are commonly removed by women practicing body nullification are: clitoris, inner or outer labia, the womb, fallopian tubes, nipples, and breasts. This may include labiaplasty and clitoridectomy, infibulation, hysterectomy, nipple removal and mastectomy. Wannabes are welcome...we want to make this a comfortable place for experienced women and girls to advise those who are considering some kind of nullification.Some nullo women are also involved with amputation of limbs. You are also most welcome.Men are NOT welcome. There are nullification groups for you and your presence may be particularly uncomfortable for girls.Group rules:1. We want to have a welcoming environment so aggressive behavior will not be tolerated.2. This is a moderated group. 3. Every upload that is off-topic will be immediately removed. 4. Male members will be immediately removed.5. This is a group for women and girls only.This group will be moderated by Amanda, an informed sympathizer and Missy, who is totally nullified and has gotten permission for arm/leg amputation._____________________________________Dies ist ein besonderer (und exklusiver) Raum fuer Frauen und Maedchen um voellige oder teilweise weibliche Nullifizierung zu diskutieren.Nullifizierung bedeutet die freiwillige Entfernung von Koerperteilen.Koerperteile, die ueblicherweise von Frauen entfernt werden, die Nullifizierung praktizieren sind: Kitzler (Klit), innere oder aeussere Schamlippen, Gebaermutter, Eileiter, Nippel und Brueste.Dies kann beinhalten: Schamlippenverkleinerung/ -entfernung, Klitorisentfernung, Infibulation (Verschliessung der Vagina), Gebaermutterentfernung, Nippelamputation, Brustamputation.Wunschkandidatinnen sind willkommen ... wir wollen dies zu einem angenehmen Raum machen, wo erfahrene Frauen und Maedchen denen Rat geben, die die eine oder andere Form von Nullifizierung ueberlegen.Einige Nullo-Frauen sind auch mit der Entfernung von Gliedmassen beschaeftigt. Ihr seid hier auch sehr willkommen.Maenner sind hier NICHT willkommen. Es gibt Nullifizierungs-Gruppen fuer Euch und Eure Anwesenheit kann besonders fuer Maedchen unangenehm sein.Gruppen-Regeln:1. Wir wollen hier eine einladende Umgebung haben, deshalb wird aggressives Verhalten nicht toleriert.2. Dies ist eine moderierte Gruppe. 3. Jeder nicht zum Thema gehoerige Beitrag wird sofort geloescht. 4. Maennliche Mitglieder werden sofort geloescht.5. Diese Gruppe ist ausschliesslich fuer Frauen und Maedchen.Diese Gruppe wird moderiert von Amanda, einer informierten Sympathisantin, und Missy, die voellig nullifiziert ist und die Erlaubnis fuer Arm-/Bein-Amputation erhalten hat._____________________________________C'est un endroit special (et exclusive) pour les femmes et filles à discuter la nullification feminine totale ou partielle. Nullification implique le déménagement volontaire des parties de corps.Parties de corps communément enlèvés par des femmes pratiquant nullification corporelle ces sont: le clitoris, les petites et grandes lèvres de chatte, l'utérus, les trompes de Faloppe, les téton, les seins entiers.Cela se peut comprendre labiaplastie, l'excision des petites lèvres, clitoridectomie, ablation des grandes lèvres, infibulation, hystérectomie, enlèvement des tétons, mastectomie, etc. Aspirantes sont bienvenues ... nous souhaitons de créer un endroit agréable pour les femmes et filles avec connaissance pour conseiller celles envisageantes quelque genre de nullification.Quelques femmes nullo avaient une liaison avec l'amputation des membres de corps. Vous êtes bienvenue le plus.Hommes ne sont pas bienvenus ici. Il y a de groupes nullification pour vous et votre présence peut être particulièrement désagréable pour les filles.Règles de groupe:1. Nous préférons un environment accueillant, par conséquent comportement aggressif n'est pas acceptable.2. Celui-ci est un groupe modéré.3.
