Human Body – 02
The circulatory system is also referred to as the cardiovascular system. It comprises the heart and all the blood vessels: Arteries, Capillaries, And Veins. There are essentially two components of circulation, namely: Systemic circulation Pulmonary circulation circulation Diagram showing Pulmonary (Blue) And Systemic Circulation (Red) Besides these two, there is a third type of circulation called Coronary circulation. Because blood is the body’s connective tissue, it helps to transport essential nutrients and minerals to the cells and waste byproducts away from it. Hence, it is also known as the Body’s “Transport System.” Anatomically, the human heart is similar to other vertebrate hearts in the animal kingdom and hence, is a homologous organ. DIGESTIVE SYSTEM A diagram of the human digestive system detailing various components: The digestive system breaks down food and assimilates nutrients into the body, which the body then uses for growth and cell repair. The major components of the digestive system are:
- Gastrointestinal tract
- Small and large intestines
- Ovaries: Produces ovum – female egg as well as the hormone estrogen.
- Uterine tubes: Oviducts or fallopian tubes are the other names given for uterus tubes.
MALE REPRODUCTIVE SYSTEM
The male reproductive system consists of testicles, which act as a storehouse for sperms. These oval-shaped organs are encased in a pouch that is called scrotum. Next to the testis is the vas deferens that are the accessory ducts for the male sexual system. When sperm is formed, it is mixed with fluids that are produced by seminal glands, prostate gland, and Cowper’s gland. The primary purpose of Cowper gland is to hike the semen volume and lubrication during coitus.
