What structure of the human body has no blood vessels?
Nails
What structure of the human body doesn't have blood vessels?
cartilage
What structure of the human body does not contain blood vessals?
nails or your hair
What structure in the earthworm has a similer function as the human heart?
In earthworms, the structure that functions similarly to the human heart is the dorsal blood vessel. This vessel acts as a pump, circulating blood throughout the worm's body. Unlike the human heart, which is a muscular organ, the dorsal blood vessel contracts rhythmically to propel the blood, helping to transport nutrients and oxygen to various tissues.
In the human heart the muscular structure of the ventricles enables them to?
Pump blood directly to the atria.
What is the most abundant structure in the human body?
Blood vessels are the most abundant structures
What structure in the leg of a human is found to carry oxygen-rich blood cells?
Its carries "oxygen rich blood" away from the heart.
What is the Difference between human blood from animal blood?
Human blood contains different types of cells (red blood cells, white blood cells, and platelets) compared to animal blood. Additionally, human blood is rich in hemoglobin, which carries oxygen, while some animals have other proteins that serve a similar function. The composition and structure of blood components also vary between human and animal blood.
What structure in the arm of a human is found to carry oxygen red blood cells and if so what do they also contain?
The structure in the arm of a human that carries oxygen-rich red blood cells is the blood vessels, specifically the arteries. Arteries transport oxygenated blood away from the heart to various tissues, including those in the arm. In addition to red blood cells, which contain hemoglobin to bind and transport oxygen, blood also contains white blood cells for immune defense and platelets for clotting.
What cell structure?
They are found in the human body such as: skin cells red blood cells white blood cells sperm cells nerve cells etc. Thanks.
A structure in the leg of a human is found to carry oxygen-rich red blood cells. What else is most likely true about this structure?
It carries blood toward the heart.
What are similarities between the human blood smear and the frog blood smear under microscope?
Numerous differences can be seen between frog blood and human blood. Perhaps the most obvious is the oval shape of the frog erythrocytes rather than the biconcave discs of human blood. Moreover, the frog erythrocytes have a nucleus (here stained blue) whilst human erythrocytes do not. There is less difference in size between the erythrocytes and leucocytes than in human blood. There are no platelets in frog blood.
