Explanation

Mitral valve: Also known as the bicuspid valve, it is located between the left atrium (upper chamber) and the left ventricle (lower chamber) of the heart. 

Other heart valves:

Tricuspid valve: Located between the right atrium and right ventricle. 

Pulmonary valve: Located between the right ventricle and the pulmonary artery. 

Aortic valve: Located between the left ventricle and the aorta. 

Explanation

 Collagen: This is the most abundant structural protein in the human body and is the primary component of the extracellular matrix of connective tissues such as bones, tendons, ligaments, and skin.

Explanation

The Radius is a bone found in the arm. 

Femur: The femur, or thigh bone, is the longest and strongest bone in the body and is located in the leg.

Semum: This is not a bone in the human body. The word may be a typo for another term.

Patella: The patella, also known as the kneecap, is the bone located in front of the knee joint. 

Explanation

The two primary shoulder bones listed are the clavicle (collarbone) and the scapula (shoulder blade). 

Explanation

The nephron is the microscopic structural and functional unit of the kidney

There are almost 1000000 of nephrons in each kidney in the human body

How it Works 

Filtration:

Blood enters the glomerulus, where its smaller components are filtered into the Bowman's capsule.

Reabsorption:

As the filtered fluid moves through the renal tubule, essential substances (water, minerals, nutrients) are reabsorbed into the bloodstream.

Waste Concentration:

The remaining fluid, now concentrated with wastes and excess water, becomes urine.

Explanation

Nephrons are the microscopic, structural, and functional units of the kidneys.

They are responsible for filtering waste products from the blood to produce urine,

This helps to regulate the body's fluid and electrolyte balance and maintain homeostasis. 

Explanation

 The majority of food digestion is completed in the small intestine.

While digestion begins in the mouth and stomach, the small intestine,

With its three sections (duodenum, jejunum, and ileum),

It is where most chemical digestion and nutrient absorption occur,.

The pancreas and liver also contribute enzymes and bile to the small intestine to aid in this process. 

Explanation

The majority of nutrient absorption in the digestive system occurs in the small intestine,

Where the final stages of digestion take place.

This organ's structure, featuring villi and microvilli, creates a large surface area optimized for absorbing digested nutrients and most water into the bloodstream.

Explanation

The function of kidneys is to remove toxins or waste products from your blood.

Kidneys keep the right amount of water in the body.

Your kidneys also help control your blood pressure.

Explanation

• Marker of bone formation are Osteocalcin
• Bone Markers are Blood and Urine tests that detect products of bones.
• Osteocalcin is a protein that helps to regenerate bone tissue.
• All are important markers of bone formation except hydroxyproline which is a marker for wound healing.
