What is the most abundant type of tissue in the human body?.

The pituitary gland is commonly known as the “master gland” because it controls the hormone production of other glands. It secretes nine hormones that regulate growth, metabolism, reproduction, stress response and more.

Choice B. Endocrine is wrong because endocrine is not a specific gland, but a system of glands that produce hormones.

Choice C. Thyroid is wrong because thyroid is a gland that produces hormones that regulate metabolism, growth and development.

It does not control other glands.

Choice D. Liver is wrong because liver is not an endocrine gland, but an organ that performs many functions such as digestion, detoxification and blood clotting.

It does not produce hormones that regulate other glands.

Normal ranges for pituitary hormones vary depending on the type of hormone, age, sex and other factors.

For example, the normal range for growth hormone in adults is 0.4 to 10 nanograms per milliliter (ng/mL), while the normal range for prolactin in women who are not pregnant or breastfeeding is 4 to 23 ng/mL.

The epiphyseal plate is the region of bone elongation that consists of hyaline cartilage and allows the bone to grow in length. If the fracture occurs in this area, it can damage the growth plate and affect the future growth of the bone.

Choice A) Diaphysis is wrong because it is the shaft of the bone that contains the medullary cavity and does not contribute to bone growth.

Choice B) Articular cartilage is wrong because it is the thin layer of cartilage that covers the ends of bones and reduces friction in joints.

It does not affect bone growth.

Choice D) Medullary cavity is wrong because it is the hollow space within the diaphysis that contains bone marrow.

It does not affect bone growth.

Normal ranges for bone growth vary depending on age, sex, and genetics. Generally, boys have a longer growth period than girls and reach their peak height around 18 years old, while girls reach their peak height around 16 years old. The average adult height for males is 69 inches and for females is 64 inches.

Connective tissue is the most abundant type of tissue in the human body. It is widely distributed and varied, and it includes fibrous tissues, fat, cartilage, bone, bone marrow, and blood.

Choice A is wrong because muscle tissue is not the most abundant type of tissue in the human body. It constitutes around 40% of total body weight and has around 700 muscles.

Choice B is wrong because nervous tissue is not the most abundant type of tissue in the human body. It consists of neurons and neuroglia that transmit and process information.

Choice C is wrong because epithelial tissue is not the most abundant type of tissue in the human body. It covers the body and many of its parts, and forms glands.

Pulmonary vein. This is because the pulmonary vein is the only vessel that carries oxygenated blood from the lungs to the heart. The blood then enters the left atrium of the heart and then the left ventricle.

Choice B. Inferior vena cava is wrong because it carries deoxygenated blood from the lower body to the right atrium of the heart.

Choice C. Aorta is wrong because it carries oxygenated blood from the left ventricle of the heart to the rest of the body.

Choice D. Pulmonary artery is wrong because it carries deoxygenated blood from the right ventricle of the heart to the lungs.
