How are gasses exchanged in the alveoli

Biology
1 answer:
Vaselesa [24]3 years ago
4 0

Answer:

The alveolar walls and capillary walls share a membrane. That's how close they're getting. This allows oxygen and carbon dioxide to readily pass from the respiratory system to the circulation. Oxygen molecules bind to red blood cells as they return to the heart.

Age why does the skeletal system become more brittle and susceptible to breakage?
dusya [7]

After age 50, bone breakdown (resorption) outpaces bone formation and bone loss often accelerates, particularly at the time of menopause.

What is Osteoporosis ?

Osteoporosis causes bones to become weak and brittle — so brittle that a fall or even mild stresses such as bending over or coughing can cause a fracture. Osteoporosis-related fractures most commonly occur in the hip, wrist or spine. Bone is living tissue that is constantly being broken down and replaced.

Osteoporosis is a disorder where your bones become brittle, fragile, and easily breakable as you age because certain minerals begin to leach out of them. Because estrogen, which helps keep bones strong, is lost during menopause, women over 50 are particularly at risk for osteoporosis.

What are some ways that the biosphere interacts with other three components of the Earth system?
Ivenika [448]

Answer:

These spheres are closely connected. For example, many birds (biosphere) fly through the air (atmosphere), while water (hydrosphere) often flows through the soil (lithosphere). In fact, the spheres are so closely connected that a change in one sphere often results in a change in one or more of the other spheres.
