Answer 1

1.Adrenal gland

The adrenal glands are small glands located on top of each kidney. They produce hormones that you can't live without, including adrenaline,the steroids aldosterone and cortisol. Cortisol helps you respond to stress and has many other important functions.

2.Artery, Vein, & Capillaries

Arteries take the oxygenated blood from the heart is carried through the body by a complex network of blood vessels. Arteries take blood away from the heart. The main artery is the aorta that branches into other major arteries, which take blood to different limbs and organs.

Capillaries are very thin blood vessels that were first discovered in frog lungs in 1661. They bring nutrients and oxygen to tissues and remove waste products. In this lesson, you will learn more about their structure and function.

Veins  are responsible for returning deoxygenated blood back to the heart after arteries carry blood out. Veins have much thinner walls than arteries. Because the pressure within them is low, veins have valves inside them to keep blood flowing only one way.

3.Bladder

The urinary bladder is a hollow elastic organ that functions as the body's urine storage tank. Urine produced by the kidneys flows through the ureters to the urinary bladder, where is it stored before passing into the urethra and exiting the body.

4.Blood sme

A blood smear is a blood test used to look for abnormalities in blood cells. The three main blood cells that the test focuses on are:

(a).red cells, which carry oxygen throughout your body.

(b).white cells, which help your body fight infections and other inflammatory diseases.

(c)platelets, which are important for blood clotting.

5.Colon

The colon is part of the large intestine, the final part of the digestive system. Its function is to reabsorb fluids and process waste products from the body and prepare for its elimination. The colon consists of four parts: descending colon, ascending colon, transverse colon, and sigmoid colon.

6.Duodenum

The duodenum is the first part of the small intestine. It is located between the stomach and the middle part of the small intestine, or jejunum. After foods mix with stomach acid, they move into the duodenum, where they mix with bile from the gallbladder and digestive juices from the pancreas.

7.Esophagus

The esophagus is a muscular tube connecting the throat (pharynx) with the stomach. The esophagus is about 8 inches long, and is lined by moist pink tissue called mucosa. The esophagus runs behind the windpipe (trachea) and heart, and in front of the spine.They keep food and secretions from going down the windpipe.

8.Intercalated Discs

Intercalated discs are microscopic identifying features of cardiac muscle. Cardiac muscle consists of individual heart muscle cells (cardiomyocytes) connected by intercalated discs to work as a single functional organ or syncytium.

9.Kidney

The kidneys remove wastes and extra water from the blood to form urine. Urine flows from the kidneys to the bladder through the ureters. The wastes in your blood come from the normal breakdown of active muscle and from the food you eat. Your body uses the food for energy and self-repair.

10.Liver

The liver also detoxifies chemicals and metabolizes drugs. As it does so, the liver secretes bile that ends up back in the intestines. The liver also makes proteins important for blood clotting and other functions.

11.Lung

Oxygen enters our lungs as part of the air that we breathe. It goes to the blood vessels deep in our lungs and then on to all parts of our body. As our body uses oxygen, it makes a waste product called carbon dioxide. We get rid of carbon dioxide when we breathe out.

12.Muscle: 3 types

There are three types of muscle, skeletal or striated, cardiac, and smooth. Muscle action can be classified as being either voluntary or involuntary. Cardiac and smooth muscles contract without conscious thought and are termed involuntary, whereas the skeletal muscles contract upon command.

13.Ovary

The ovaries produce and release eggs (oocytes) into the female reproductive tract at the mid-point of each menstrual cycle. They also produce the female hormones oestrogen and progesterone.

14.Pancreas

The Pancreas and Its Functions. The pancreas is an organ located in the abdomen. It plays an essential role in converting the food we eat into fuel for the body's cells. The pancreas has two main functions: an exocrine function that helps in digestion and an endocrine function that regulates blood sugar.

15.Parotid gland

The parotid gland is a salivary gland, responsible for making saliva. There are two parotid glands, one on each side of the face. They are located in front of the ears and extend to the lower borders of the jawbones. The glands secrete thin saliva which travels into the mouth to aid in chewing and digesting food.

16.Stomach

The stomach is a muscular organ located on the left side of the upper abdomen. The stomach receives food from the esophagus. As food reaches the end of the esophagus, it enters the stomach through a muscular valve called the lower esophageal sphincter. The stomach secretes acid and enzymes that digest food.

17.Testis

The testicles are housed in the scrotum just behind the penis. The testicles are the male gonads — the primary male reproductive organs. They have two, very important functions that are very important to the male reproductive system: they produce gametes, or sperm, and they secrete hormones, primarily testosterone.

18.Thyroid gland

The thyroid gland is a vital hormone gland: It plays a major role in the metabolism, growth and development of the human body. It helps to regulate many body functions by constantly releasing a steady amount of thyroid hormones into the bloodstream.

19.Trachea

Trachea (Windpipe) The trachea (or windpipe) is a wide, hollow tube that connects the larynx (or voice box) to the bronchi of the lungs. It is an integral part of the body's airway and has the vital function of providing air flow to and from the lungs for respiration.
