Introduction
1. As we continue our study of evidence that God Is, we will next look at the human body for such Divine Construction.
2. Our bodies are a wonderful thing to behold. The Psalmist agreed with this assessment of man when he penned “I will praise thee; for I am fearfully and wonderfully made: marvelous are thy works: and that my soul knoweth right well (very well) Psalm 139:14.
3. “And the Lord God formed man of the dust of the ground, and breathed into his nostrils the breath of life: and man became a living soul” Genesis 2:7.
4. As we take a brief tour of the human body, it won’t take long for us to realize, that its construction is not some fluke of evolution, taking millions of years of time to pass for all these different variables to fall into place.
5. We will also feel the need to give thanks to the Almighty God for such a gift.
I. The Human Brain.
A. The Lord Jesus searches the minds and the hearts of men. “I am He which searcheth the reins (minds) and hearts” Revelation 2:23.
B. “But Jesus did not commit Himself unto them, because He knew all men, and needed not that any should testify of man: for He knew what was in man” John 2:24-25.
C. “Who hath made man’s mouth”? Exodus 4:11.
D. The human brain is not much to look at. It weighs about 3lbs. and is a wrinkly, blob of tissue.
E. Our scientists still do not understand completely how the human brain works, but they have made some progress in understanding it.
F. The brain with all of its 20 billion neurons, millions of synapsis, numerous centers (speech, thoughts, emotions, millions of memory cells) is likened to a computer center that is not like any other. Millions of nerve ganglia (strips of nerve fibers) that connects signals from one center of the brain to another.
G. Four specific parts of the human brain.
1. Fore brain. Consisting of the cerebrum. Intellectual activities, memories, planning, imagination, reading, logic.
2. Mid brain. Controls reflexes, eye movement, voluntary muscle movements.
3. Hind brain. The brain stem. The cerebellum. Controls breathing, heart rate, autonomic responses.
4. Then there is the inner brain.
a. Deep inside the groove that separates the two halves of the brain. In the inner brain is the hypothalamus, the size of a pearl, wakes you up in the morning, cause the adrenaline flowing when called upon. Also the hypothalamus is the emotion control center of the brain.
b. Thalamus connecting and storing information going to and from the brain and the spinal cord.
c. Hippo-campus. Small nub sends out memories for long term storage. Also the center for retrieval of memories.
5. Basal ganglia- nerve cells strips surrounding the thalamus responsible for initiating integral movements. Parkinson disease is the end result of these ganglia not making contact.
H. As you can see this complex organ made of flesh and blood cannot be the outcome of millions of years of evolution for it all come together as we know our brains to function.
II. The Human Skeleton.
A. The internal framework of the human body.
B. Each part of the skeleton has an important function.
1. Skull. Protects the brain. Made of bone. Thick in the right places. Cutouts for eyes, nose, mouth and ears.
2. Connected to the skull is the vertebrae column. Protecting the spinal cord.
3. Next is the shoulder girdle. Shoulder blades connected to the rib cage. Lungs, heart protected from injury. How many ribs?
4. The pelvis. Protecting the reproductive organs. Connected to the hips.
5. Arms, legs, hands and feet. Arms and legs equipped for bearing burdens, loads. Fingers and toes for dexterity.
C. Six major functions of the skeleton. Support, movement, protection. Bones which produce blood cells, storage of minerals, marrow.
D. Connected to the bones are tendons, muscles. Like pulley systems in the body.
E. Joints between bones that allow movement.
F. At birth the human skeleton has 270 bones. After the age of 13, some of these bones will fuse together for strength. Every man and woman from this time will have 206 bones.
G. Consider Job 10: 8-13. Even the Job knew who had formed his bones together.
III. Glands Of The Human Body.
A. There are 42 different kinds of endocrine glands that secrete different substances throughout the body through a myriad of duct works.
B. There are 9 different types of endocrine glands that secrete hormones, minerals through the blood. Veins, arteries. Such as the thyroid gland, the heart, the stomach, the intestines etc.
C. There are 8 different types of integument glands (skin glands) that deliver moisture to the eyelids, ears, genitals. Sweat is one of these glands that cool the body temperature down.
D. Who told these little bitty fellows to do all these things?
V. The Human Heart.
A. An organ, a muscle that pumps billions of gallons of blood in a lifetime.
B. The blood it pumps supplies the body with oxygen and delivers nutrition to tissues while at the same time removing carbon dioxide and other waste.
C. The human heart weighs about 10-12 ounces in men, 8 to 10 ounces in women, roughly the size of your fist.
D. The human heart has four chambers. Two upper, two lower. A wall of thick muscle separates the two sides of the heart.
E. There are different types of valves in the human heart.
1. Tricuspid valve and mitral valve connect the atria to the ventricles.
2. The pulmonary valve separates the right ventricle from the pulmonary artery.
3. The aortic valve separates the left ventricle from the aorta.
F. The sinoatrial node produces the electrical pulses that drive heart contractions.
G. One side of the heart pumps blood out, while the other brings blood.
V. Human Blood.
A. Blood is specialized bodily fluid that supplies essential substances and nutrients, such as sugar, oxygen, hormones to our cells and organs.
B. There are different types of blood.
1. Red blood cells. They contain hemoglobin. This is a protein which contains iron, transports oxygen to lungs and body tissues and cells. They have a 4 month life span. They are depleted and new ones replace them.
2. White blood cells. Fight abnormal cells such as cancer cells.
3. Platelets. Involved in clotting of blood. If exposed to the air, they break down and release fibrinogen into the bloodstream, which causes scabs to grow on cuts.
C. Different types of blood. Type A, B, AB & O.
Conclusion
1. All of these things and their functions connected to the human body are indeed marvelous to contemplate upon.
2. Not some accident, not some jumbling of millions of variables, but all given, planned by God Almighty.
3. If man cannot and will not see these simple illustrations of God’s Divine plan of the human body, then perhaps a faith check is needed!
