Cell basics- Lysomes
What are the properties of a lysosome?
Lysosomes are organelles found inside plant and animal cells, but not in bacteria cells.

They are important because lysosomes help break down old cell parts and and digest materials brought into the cell. They might be used to digest food or break down the cell when it dies.
Lysosomes have a single membrane and are filled with digestive enzymes.
A lysosome is created at the Golgi apparatus.
The proteins of the lysosome are created at the rough ER and are packed in a vesicle that is transported to the golgi apparatus. The golgi apparatus uses these proteins to make digestive enzymes and creates a vesicle that pinches off.
This vesicle is a lysosome
Lysosomes are found in the cytoplasm.
When materials are brought into the cell lysosomes can attach to these objects and begin to break them down.
Lysosomes will also break down other organelles like mitochondria if the cell does not have any food or the mitochondria is working improperly.
Lysomes will even digest bacteria that enters the cell.

What happens in prophase?
Cell Division Crossword Puzzle

Prophase is the first stage of mitosis.
During prophase, the chromosomes first begin to appear.
Next, the nuclear membrane begins to break down, and the centrioles produce mitotic spindle fibers.

Three types of circulation in the body
Three types of circulation in the body Teacherflix 4 צפיות • לִפנֵי 2 שנים

In this video I will talk about three types of circulation found in the human body. lymphatic circulation and two types of blood circulation. Pulmonary circulation and systemic circulation.
Let’s look at blood circulation first.
Your blood is responsible for carrying oxygen, waste, sugar, and other important items throughout your body.
In order to carry oxygen and eliminate carbon dioxide it must travel to the lungs. Pulmonary circulation is when blood travels to the lungs and back. Blood enters the right atrium from the superior and inferior vena cava. It travels to the right ventricle and into the lungs through the pulmonary arteries. In the lungs oxygen is exchanged for carbon dioxide at tiny air sacs called alveoli and then returns to the heart through the pulmonary veins.
Up next is systemic circulation which is circulation throughout the body. As blood returns from the lungs it enters the left atrium then travels to the right ventricle then passes out the aorta and into the rest of the body. This circulation is called systemic circulation.
Three types of vessels are used for blood circulation.
An artery is a blood vessel that takes blood away from the heart to all parts of the body (tissues, lungs, etc). Most arteries carry oxygenated blood Arteries are usually shown as red vessels.
Veins are blood vessels that carry blood toward the heart. Most veins carry deoxygenated blood from the tissues back to the heart both of which carry oxygenated blood to the heart. Veins are usually shown as blood.
Capillaries are tiny vessels that connect arteries and veins.

The third type of circulation is called lymphatic circulation.
The lymphatic system absorbs and transports lymph. Lymph is a clear fluid that is a result of plasma leaking out of capillaries.As plasma moves out of capillaries, some of it is not reabsorbed. You lose around three liters of the plasma a day. The lymphatic system reabsorbs lose fluid.
If you look at this cross section of a tissue you can notice how the lymphatic vessel is located near the vein.
Once this plasma that has leaked out of capillaries and enters lymphatic vessels it is called lymph
Lymph also includes protein and cellular debris which are too large to be collected by veins and capillaries.

The lymphatic vessels have smooth muscle and valves that help move the lymph throughout your body.
