Whats are the functions of the integumentary system ?
Verdich [7]

Answer:

Absorption

Thousands of pores on the surface of the skin can absorb vitamins, acids, water and oxygen in order to provide moisture and nourishment to our skin.

Excretion

The skin is the body’s largest waste removal system. Toxins are released through the sweat glands and pores.

Secretion

The skin secretes sebum, a mixture of oils that keeps the skin soft and supple. The layer of sebum on the outermost layer of the skin is known as the acid mantle. When intact the acid mantle has a PH that ranges from 4.5-5.5. The acid mantle is acidic in nature to protect the skin from outside invasion.

Regulation

The skin regulates the body’s temperature by sweating; when water from sweat on the skin evaporates it gives off heat and cools the body.  The body’s temperature increases or by shivering or getting goosebumps when the body is cold. The contraction of muscles releases energy that warms the body.

Sensation

The skin contains millions of nerve endings that transport stimuli. These nerve endings allow humans to detect sensation such as heat, cold, pain and pressure.

What must take place in the lungs prior to the newborn's first breath? A. Blood must be drained from the alveolar capillaries B.
Iteru [2.4K]

Answer: Drainage or absorption of amniotic fluid

Explanation: Amniotic fluid act as a cushion to a growing foetus and provides the foetus with nutrients and biochemical products from the mother via the blood vessels of the placenta. When the date of baby delivery grows closer the lungs absorbs some of the fluid. Soon after birth the newborn's first step to independence begins with breathing on its own.They gasp and cry taking in air that fills the lungs. This expels the remaining amniotic fluid that was in the lungs and begins its own independent breathing.
