The Hierarchy in Organization of . Living Things

Circulatory System

The system that transports oxygen and nutrients throughout the body and carries away wastes

The heart pumps blood

The blood travels to large arteries

Then travels to the small vessels

Blood exchanges many substance with the surrounding tissues

Blood flows into the veins

Blood returns back into the heart, process repeats

Heart

Made up of tissues

Cardiac Muscle Tissue

Makes the heart contract and moves the blood around the body

Nerve Tissue

Connective Tissue

Blood vessels

Types

Arteries

Veins

Carry blood away from the heart

Capillaries

Tiny blood vessels with very thin walls which allow substances to diffuse between the blood and other body fluids and tissues

Blood

Type of Protein

Plasma

A protein- rich liquid that carries the blood cells along and makes up over half of blood's volume

Types of Blood Cells

Platelets Cells

Tiny cells that help in blood clotting

White Bell Cells

These are infection- fighting cells in the blood which recognize and destroy invading bacteria and viruses

Red Blood Cells

Contains a protein called hemoglobin, which allows them to transport oxygen throughout the body

Digestive System

Organ system which both chemically and mechanically break down food to release nutrients molecules for our body to absorb and use
Digestion

When you eat, you swallow and your tongue pushes the food into your throat.

Digestion-Breaks food down into useful nutrients

Salvary Glands

Esophagus

Once you begin swallowing, the food begins to move down your esophagus

Stomach

Food enters your stomach, the stomach muscles mix the food and liquid then slowly empties its liquids, called chyme

Absorption-Nutrients move into the bloodstream

Liver

The food then eneters the small intestine. The muscles of the small intestine mix food with digestive juices from the pancreas, liver, and intestine, and push the mixture forward.

Pancreas

Appendix

Small Intestine

Large Intestine

Moving into the large intestine, the large intestine absorbs water and changes the waste from liquid into stool

Anus

To food moves down to the rectum, stores stool until it pushes stool out of your anus

Elimination-Leftover waste is removed from the body

Rectum

Respiratory system

Organ system provides oxygen for the body and allows carbon dioxide to leave the body
Stages

Air first begins to enter our body from our mouth and nose

Passes through the pharynx

Travels down the trachea

Trachea Support

Trachea is supported by many rings of cartilage. The cartilage keeps the trachea open to allow air to flow freely. It is a special type of connective tissue with specialized cells mixed in a mix of strong and flexible fibres.

Trachea divides into 2 bronchus known as the bronchi

Organs

Mouth

Nose/ Nasal Cavity

Pharynx

Trachea

Bronchi

Lungs
