🎯For freshman students CoC preparation 🧫HORMONES & THEIR FUNCTIONS 1. Growth hormone (GH) Or somatotropic hormone (STH) Function ~ stimulates growth by stimulating protein synthesis. 2. Thyroid stimulating hormone (TSH) Function ~ stimulates thyroid secretion. 3. Adrenocorticotropic hormone (ACTH) Function ~ stimulates the production of of steroids by adrenal cortex. 4. Gonadotropic hormones (i) follicle stimulating hormone (FSH) Function ~ stimulates gamate, production, secration of sex hormones, development of follicles. (ii) interstitial cell stimulating hormone ( ICSH) or luteinising hormone (LH) Function ~ stimulates the leydig cells of testis and induces secretion of testosterone. stimulates development of Corpus luteum and ovulation in female. 5. Luteotropic hormone ( LTH) or prolactin Function ~ stimulates the growth of mammary glands, lactation and maintenance of Corpus luteum. 6. Melanocyte stimulating hormone Function ~ controls dispersal of melanophores , in man it is doubtful. 7. Oxytocin Function ~ stimulates secretion of milk from mammary glands ; causes contraction of uterus at the time of child birth. 8.

🎯 For freshman students 📚 CoC exam about general biology 🔬Blood Group 📌Introduction Based on the presence and absence of antibodies, the blood is classified into different groups. 📌Further, while classification, the presence and absence of the inherited antigenic substances also considered. 📌The types of blood groups are inherited and represent contributions from both the father and the mother. The main components of blood are: 📌red blood cells, which carry oxygen around the body 📌white blood cells, which play a crucial role in the immune system 📌plasma, which is a yellowish liquid that contains proteins and salts 📌platelets, which enable clotting 📌there are two types of antigens to classify blood types: 🚿ABO antigens 🚿Rh antigens ABO Blood Group System 📌Red blood cells are special cells in our body. They do not have nuclei. Because there is no nucleus in a red blood cell, it cannot multiply through cell division because for a cell to undergo cell division, a nucleus is necessary. Thus, red blood cells simply die out after 120 days. 📌In human blood, usually, there are two antigens and antibodies. 📌The two antigens are antigen A and antigen B. 📌The two antibodies are antibody A and antibody B. 📌The antigens are remaining in the red blood cells, whereas the antibodies are found in the serum. 📌Based on the antigen property, the blood group of all human beings can be classified as − ➭ Blood Group A − antigen A and antibody B ➭ Blood Group B − antigen B and antibody A ➭ Blood Group AB − antigen A and antigen B and no antibody ➭ Blood Group O − no antigen, but antigen A as well as antibody B ➖Consideration of the ABO system is the most imperative while transfusion of human blood. 📌The ABO blood group systems were first discovered by Karl Landsteiner in 1901. 🚿Rh Blood Group System 📌The Rh system (the meaning of Rh is Rhesus) is another significant blood-group system. It is very important to match Rh system while blood transfusion. 📌Rh antigen first studied in Rhesus monkeys; therefore, its name is given Rh factor/system. 📌The person who does not have Rh antigen is known as Rh negative (Rh-ve) and the person who has the Rh antigen is known as Rh positive (Rh+ve). ╔════════════ 📚JOIN: @Ethio_universityinfo 📚JOIN: @ethio_universitychat ╚═══════════
