A. Pick 3 of the following and argue that the following are either “adaptive” or necessary for survival, homeostasis, and/or reproduction:
1. Adluminal compartment of seminiferous tubules
• The adluminal compartment is made up of spermatocytes, spermatozoa and spermatids. The compartment is considered a tight-junction. This tight-junction is said to be a blood-testicle-barrier. This means the spermatozoa found in the adluminal compartment are kept behind the barrier and away from the blood circulation of the lymphatic system. If the spermatozoa were capable of escaping the compartment the body would produce antibodies work against the antigens present …show more content…
Identify the benefits of each secretion produced by the following:
1. Uterine glands
• The uterine glands secrete a glycogen-rich product. This secretion of glycogen-rich product takes place after ovulation. The substance being secreted is key for the development and survival of a fetus/embryo.
2. Leydig cells
• Leydig cells form and secrete testosterone. The testosterone is secreted in response to the lutenising hormone. Spermatozoa production is promoted by the testosterone secreted. The testosterone being secreted by the Leydig cells are important for the formation of secondary characteristics of the male.
3. The different pancreatic cells
• One of the pancreatic cells is the exocrine gland. The exocrine gland secretes out different types of enzymes. The enzymes secreted break down different products of food such as the carbs, proteins, lipids and nucleic acids. The other type of cell is the endocrine gland. The endocrine gland secretes out different types of hormones. The hormones being secreted are glucagon and insulin. These two hormones being secreted are a big part in the control of our blood sugar levels. Di
D. Where are these found in the body and how does each represent a physiological interface (i.e. how does each interact with surrounding
