It is in the respiratory system.
They give live birth, their young suckle and they breathe with lungs.
no dude one of the things that is classified as a male is breath through lungs!
Pulmonology is a medical study that deals specifically with problems regarding the lungs and the respiratory tract.
The layer of cells in the air passages that clean the air before it reaches the lungs is best classified as the respiratory mucosa or respiratory epithelium. These cells are equipped with cilia and mucus that trap and remove dust, particles, and pathogens from the inhaled air, helping to protect the lungs from potential harm.
They don't give birth to live young, they don't suckle their young, they are cold blooded
Organs such as the brain, liver, lungs, spleen, and kidneys are classified as soft organs because they are delicate and vulnerable to damage. These organs have a softer texture compared to others like the bones or muscles.
Monotremes are still classified as mammals because the young suckle on mother's milk. No other animal among the vertebrates does this - only mammals. They are also warm blooded and breathe through lungs, like mammals.
The kiwi is a bird because it satisfies all the criteria of a bird. It is a warm-blooded vertebrate that breathes through lungs. It has feathers and lays eggs.
The pulmonary veins carry blood from the lungs to the left atrium of the heart.*Because blood vessels are classified by whether they lead into or away from the heart, the pulmonary veins are the only veins in adults that are carrying oxygenated blood, whereas the pulmonary arteries carry deoxygenated blood from the right ventricle to the lungs.
Mermaids, if they existed, would likely be classified as mammals because they have a human-like upper body believed to have lungs for breathing air. Their fish-like tail would not necessarily categorize them as fish, as some mammal species also have tails.
Pulmonary arteries.* Blood vessels are classified by whether they flow to or from the heart. The pulmonary arteries carry deoxygenated blood from the body to the lungs, and it is the pulmonary veins that carry oxygenated blood back to the left side of the heart, where it is pumped to the body.
Hemoglobin is classified as a globular protein and a metalloprotein because it contains iron, which is essential for its function in oxygen transport. It is composed of four polypeptide chains, typically two alpha and two beta chains, each containing a heme group that binds oxygen. Hemoglobin is found in red blood cells and plays a crucial role in transporting oxygen from the lungs to tissues and facilitating the return of carbon dioxide from tissues to the lungs.
