Answer:
It has four main components: plasma, red blood cells, white blood cells, and platelets. Blood has many different functions, including transporting oxygen and nutrients to the lungs and tissues
Explanation:
Plasma is the main component of blood and consists mostly of water, with proteins, ions, nutrients, and wastes mixed in. Red blood cells are responsible for carrying oxygen and carbon dioxide. Platelets are responsible for blood clotting. White blood cells are part of the immune system and function in immune response.

Considered to be homologous structured similarities, they are different due to evolution and how they were used over thousands of years, eventhough they are all similar because of a common ancestor.

Bethanechol [Urecholine]
Bethanechol [Urecholine] is given orally for treating glaucoma. Direct-acting cholinergic drugs such as carbachol [Carboptic] are also used to treat increased intraocular pressure in conditions such as glaucoma and have positive effects when administered topically in the form of eye drops but are poorly absorbed when administered orally. Pilocarpine [Salagen, Pilocar] also has poor absorption capacity when administered orally for the treatment of intraocular pressure. However, it can be used orally for treating dry mouth (xerostomia). Drugs such as donepezil [Aricept] and galantamine [Razadyne] are indirect-acting drugs and are mostly used to treat neurological disorders such as Alzheimer's disease.
<u>Answer:</u>
<em>An LH spike occurs during oestrogen feedback loop because the pituitary gland positively responds to the high level of oestrogen </em>and produces more LH.
During the ovulatory phase the amount of hormones like oestrogen, follicle stimulating hormone and Leutenising hormone are high. <em>FSH enables the formation of follicles and LH enables the rupture of matured follicle and release of ovum into the oviduct. </em>
In the middle of menstrual cycle when the amount of oestrogen is high pituitary gland give <em>a positive feedback by producing more LH.</em>
<em>This is called LH surge.</em> By this time primary follicles would have matured into graffian follicle and would be holding the ovum. <em>LH surge causes the follicle to rupture and the ovum gets released into the oviduct. </em>
