Circulation of the blood inside our body

1. Unit 11: BLOOD
Discussant: Joy Nadate
Lloyd Mationg
BSEd- Science 3-2

2. At the end of the lesson the students should
be able to :
2
1. describe the composition, functions, and importance of
blood in the human body,
2. demonstrate the ability to collect and process blood
samples safely and accurately; and
3. appreciate the importance of blood and its components
in maintaining overall health and preventing disease.

3. Blood
A specialized bodily
fluid, acting as a type of
connective tissue, that
circulates through the
circulatory system to
deliver oxygen and
nutrients to cells while
removing waste
products.
3

4. Fuctions of the blood
Transporting oxygen to
cells and removing
carbon dioxide, delivering
nutrients, hormones, and
removing waste products.

1.Transportation

5. Fuctions of the blood
Regulating pH, body
temperature, and water
balance to maintain
homeostasis.
5
2. Regulation

6. Fuctions of the blood
Protecting the body
through clotting when
vessels are damaged and
defending against
infections via white blood
cells and antibodies.

7. 1. Plasma: Makes up about 55%
of the total blood volume.
2. ​Formed Elements: Makes up
about 45% of the total blood
volume. This includes:
Composition of the blood
Blood is made of two major parts:
7

8. Formed elements:
Red blood cells(Erythrocytes)
8
Most numerous; responsible for oxygen
transport.
White Blood Cells (Leukocytes):
Involved in immune defense.
Platelets (Thrombocytes):
Involved in blood clotting.

9. Terminology used with enzymes
To understand how enzymes work, it’s important to
know some key terms:
9
1. Enzymes
Is a biological catalysts, most
often proteins, that accelerate
specific chemical reactions
within living organisms without
being consumed in the process.

10. Terminology used with enzymes
To understand how enzymes work, it’s important to
know some key terms:
10
2. Substrate
The substrate is the
substance the
enzyme acts on.

11. Terminology used with enzymes
To understand how enzymes work, it’s important to
know some key terms:
11
3. Active site
is the specific part of
the enzyme where the
substrate binds.

12. Terminology used with enzymes
To understand how enzymes work, it’s important to
know some key terms:
12
4. enzyme–substrate complex
is the temporary
combination formed
during the reaction.

13. Terminology used with enzymes
To understand how enzymes work, it’s important to
know some key terms:
13
5. product
is the final substance
produced after the
reaction.

14. Terminology used with enzymes
To understand how enzymes work, it’s important to
know some key terms:

15. Plasma is the straw-
colored liquid component
of blood, serving as the
medium for all other blood
components.

16. PlasmaComposition
​Plasma is approximately:
16
•​92% Water: Acts as a solvent
and helps regulate body
temperature
•8% Solutes: Includes proteins,
electrolytes, nutrients, hormones,
and waste products.

17. Plasma
​Key Solutes and Functions:
17
1. Proteins
•Albumin-osmotic balance,
transport
•Globulins- Anti-bodies,
immunity
•Fibrinogen- helps with
clotting.

18. Plasma
​Key Solutes and Functions:
18
2. Electrolytes
• Sodium(Na+), Chloride (Cl-)
3.Nutrients
• Glucose, lipids and amino
acids
4. Wastes
• Urea, Carbon dioxide (CO2)

19. Lipids in Plasma
Lipids are an important and a critical nutrient for the human
body, we have already seen its vital role in membranes across
all systems. The also act as great insulators, and many function
as signal molecules and hormones.
19
Just as there are essential amino acids, there are two fatty
acids that are essential,
1.Alpha-linolenic acid, an omega-3 fatty acid.
2.​Linoleic acid, an omega-6 fatty acid.

20. Transport of Lipids in Blood
most lipids are hydrophobic
and plasma (which is 92%
water) is hydrophilic.
Therefore, most lipids
require special mechanisms
for transport through the
blood to and from the
tissues.

21. ​The Lipoproteins in the Blood
Lipoproteins these are
protein transporters that
shuttle large amounts of
lipids in the plasma to and
from various tissues all
around the body.
21

22. 1.Ultra low density lipoprotein
also known as Very Low
Density Lipoproteins (VLDLs) -
a type of lipoprotein produced
by the liver that transports
triglycerides (a type of fat) and
cholesterol through the
bloodstream to tissues.
​Types of Lipoproteins in the Blood
22

23. 2. Low Density Lipoproteins
(LDLs)- is a particle in the
blood that carries cholesterol
to the cells, but high levels of
it are known as "bad"
cholesterol because it can
build up on artery walls,
increasing the risk of heart
disease and stroke.
​Types of Lipoproteins in the Blood
23

24. 3. High-density
lipoprotein (HDL)-is a
"good" type of cholesterol
that removes excess
cholesterol from the blood
and carries it back to the
liver, where it's processed
and eliminated from the
body.
