Biology Biology is the study of life; in this unit we talked about cells (types, what they're made up of and specialization), the cell cycle, 3 organ system, and the interactions between the different systems.

Digestion Procedure

1. Ingestion - Taking food or another substance by swallowing or absorbing it 2. Digestion - Breaking food down mechanically into nutrients that is used for energy, growth, cell repair that are needed. 3. Absorption - Simple molecules that result from chemical digestion pass through cell membranes of the lining in the small intestine into the blood or lymph capillaries. 4. Assimilation - The process of absorbing nutrients during digestion and equally distributing it for growth and repair. 5. Egestion - This is the removal of undigested food that cannot be digested any further. It is removed from being solid or semi solid with the digestive tract and through the anus.

Cell Cycle

Plant Cell Image

Animal Cell Image

Plant Cells

Plant cells are the basic unit of life in organisms and Plant cells have special organelles called chloroplasts, which create sugars with photosynthesis.

Animal Cells

Animal Cell Parts

Nucleus Ribosomes Endoplasmic Reticulum Golgi Apparatus Lysosomes Mitochondria Cytoplasm Cytoskeleton

Animal cells are enclosed by a plasma membrane and containing a membrane-bound nucleus and organelles.

Cell Divison

Cell division is the process by which a parent cell divides into two or more daughter cells

A cell cycle is a series of events that takes place in a cell as it grows and divides. ... The cell then leaves interphase, undergoes mitosis, and completes its division.

Tissue

A group of cells that have fanmilar functions with the same goal of helping the body

Connective Tissue

Support and protects the cells and tissues

Fat

Stores energy and is like a coat for organs

Red and White blood cells , Transports nutrients and oxygen , Takes care of bacteria and viruses

Bone

Movement and Support

Animal cells have different types of tissue

Cardiac Muscle

Contract as a unit

Smooth Muscle

Blood vessels and walls of organs contracts slowly

Skeletal Muscle

Movement is allowed and Cells line up in the same direction.

Nervous Tissue

Neurons send signals and receive them

Epithelial Tissue

Tissue Image

Columnar Epithelia

Columns of cells that line the organs.

Organs

Heart

Circulatory System

Circulatory System is made up from blood vessels that carry blood away and towards the heart. The circulatory system carries oxygen, nutrients, and hormones to cells, and removes carbon dioxide.

Respiratory System

The Respiratory System is responsible with all the organs to help us breathe oxygen in and removing carbon dioxide.

Gas Exchange

Exhalation

1. Diaphragm moves up 2. Rib cage goes in and down 3. Chest capacity decreases 4. Air rushes out

Inhalation

1. Diaphragm moves down as it contracts 2. Rib cage has in and out movements 3. Chest capacity increases 4. Air rushes in

The Circulatory System allows oxygen to be delivered into cells and takes out the carbon dioxide buildup.

Oxygen makes it's way in by getting inhaled and carbon dioxide gets diffused out with exhalation. Breathing in allows the lungs to expand and breathing out closes them down slowly and exchange occurs.

Digestive System

Type of Digestion

Mechanical Digestion

Food is broken down by chewing, tearing, grinding of teeth and the stomach. It is a purely physical process controlled by you and it makes food smaller to have more area.

Chemical Digestion

Food is broken down with chemicals. enzymes break the chemical bonds that hold food particles together. This allows food to be broken down into small, digestible parts
