Write the functions of muscle cells, brain cells, liver cells, blood cells, bone cell, sperm cell, ovum and intestinal cells.

Dear student,

1.  There are three different types of muscle cells in the human body.
a. Skeletal muscle cells attach to bones and bring about movement in joints. Also responsible for maintenance of posture.
b. Smooth muscle cells are found lining internal organs and blood vessels in humans, and are responsible for the contraction of organs.
c. Cardiac muscle cells make up the heart and are responsible for pumping blood throughout the body of many species.

2. Neurons commonly referred to as building blocks of brain are the cells in the brain that send and receive electrical and chemical signals to other neurons, muscles and through out the body. They allow us to think, feel, move, and comprehend the world around us.

3. Liver cells have primary role in breakdown of fat and inturn produces energy. Beside this, other functions are:
  • Bile production and excretion.
  • Excretion of bilirubin, cholesterol, hormones, and drugs.
  • Metabolism of fats, proteins, and carbohydrates.
  • Enzyme activation.
  • Storage of glycogen, vitamins, and minerals.
  • Synthesis of plasma proteins, such as albumin, and clotting factors.

4. There are different types of blood cells each performing unique functions:
a. Red blood cells help in transporting oxygen and nutrients to the lungs and tissues.
b. Platelets have a role in forming blood clots to prevent excess blood loss.
c. White blood cells carry cells and antibodies that fight infection.

5. The main function od sperm cell is to reach the ovum and fuse with it to deliver the male pronucleus that contains the genetic material.

6. The main function of the ovum is to carry the set of chromosomes contributed by the female gamete. It also creates the right environment for fertilization to occurwith the help of sperm.

7. Intestinal cells provide a physical and biochemical barrier that segregates host tissue and maintain intestinal homeostasis with the help of bacteria. It also plays a role in secretion of mucins and antimicrobial peptides.
Regards.
