3)Testis consists of germ cells, sertoli cells and leydig cells .

Germ cells produce spermatocytes and spermatids.

Sertoli cells produce oestrogen and leydig cells produce testosterone.

Ovaries consists of theca cells which produces primary oogonia which undergo development to form follicles and produce ovum.

4) The four primary tissue types are -

Epithelial tissue

It forms lining the organ system and has role in absorption, protection and secretion.

Muscle tissue

It forms muscular system essential for locomotion and movement.

Nervous tissue

It consists of functional unit called neurons and glial cells, responsible for impulse transmission and propagation.

Connective tissue

It joins the organ system and is of various types - areolar connective tissue, adipose connective tissue, blood , dense fibrous connective tissue ( regular and irregular) , bones and cartilages etc.

5) artery, veins and capillary are the parts of vascular system which along with heart forms cardiovascular system.

Also artery has its own nerve supply and is regulated by changes in the homeostasis and external environment so it adjust according to the change and maintain homeostasis under hormonal and neural regulation.
