	1.	Immunity is conferred in the body by the blood cells that are formed in our bone marrows and other locations , for these blood cells travelling throughout the  body , the body employs its extensive vasculature that is , a network of blood vessels . The blood vessels transport immunity cells throughout the whole body do them to carry out their function. Immunity in the body provides resistance to infections ,toxins and helps to overcome disease conditions. In disease conditions like COVID-19 , the importance of a strong immune system can not be over emphasised since there is currently to anti viral treatment , the blood vessels would now carry out a major  function to ensure that the immunity of the body is intact to protect the body against infections.
	2.	The subsatorial canal is also known as the adductor canal, serves as a passage way for structures moving between anterior thigh and posterior leg , the femoral artery and vein pass through this canal and give rise to the popliteal artery and vein in the distal lower limb , it also houses the saphenous nerve being the largest cutaneous branch of the femoral nerve . Adductor canal block is medical procedure in which local anaesthetic is administered in the adductor canal to block the saphenous nerve in isolation or together with the nerve to the vastus medialis . This procedure is used to provide sensory anaesthesia for procedures involving the distal thighs and femur, knee and the lower leg on the medial side, the femoral artery is used as a landmark to locate the adductor canal. Other procedures such as saphenous vein cutdown or orthopedic surgery that includes incisions or dissection over the distal tibia or medial malleolus can result in damage to the saphenous nerve, resulting in loss of cutaneous sensation in the medial leg. This is due to the intimate path that the saphenous nerve and the great saphenous vein travel. The saphenous nerve is also often damaged during vein harvest for bypass surgery and during trocar placement during knee arthroscopy. Adductor canal syndrome is a conditioning where the neurovasculsr bundle in the canal experiences an entrapment it is a rare condition mostly common to young men usually caused by hypertrophy of adjacent muscles that is , from exercises involving quadriceps muscles or prolonged walking or standing . The patient may present with claudication symptoms due to femoral artery occlusions or neurological symptoms due to entrapment of saphenous nerve .
	3.	A.The extraocular muscles are the 6 muscles that control movements of the eye and one muscle that controls the eyelid elevation. The actions of the muscles are responsible for eye movement depending on the position of the eye at the time of muscle contraction. The oculomotor nerve inervates the superior rectus muscle, inferior rectus muscle, medial rectus muscle, inferior oblique muscle, and the Levator palpebrae superioris muscle. The trochlear nerve inervates the superior oblique muscle. The abducens nerve inervates the lateral rectus muscle.                                      B. the intraocular muscles are capillary muscles inside the eye for constricting pupil and for increasing power of lenses and are innervated by the ciliary nerves.
